The desert module had a crash caused by a wrong import. It tried to get the model for the lizard from the forrest module, which caused problems. This has been solved. I also added a new mob, the scorpion! These little creatures weren't in the 1.7.10 version. They live in deserts and will attack/poison you so watch out and keep some milk at hand.

The Core module has also been updated. Ive extended the config options and disabled some unused code for faster running.
